To be sure, diet and exercise are key elements of any weight control program. In fact, we’ve instituted a very successful “mini-fast” at my Whitaker Wellness Clinic where patients replace breakfast with a workout and fast until lunch. Nutritional supplements also play an integral role in weight control. My Metabolic Essentialscontains a powerful green tea extract and other cutting-edge ingredients that target the risk factors such as blood sugar, blood pressure and cholesterol.
